Basically, I agree with these sentiments. However, I would not want the casual reader to take away from Eliot's excellent rant the idea that the relationship between objects and their XML serializations need be entirely arbitrary. The grove paradigm permits interchangeable information and ready-to-use objects to be quite precise, rigorous, and non-arbitrary reflections of one another. The exact nature of the relationship between the two kinds of information can be expressed in an Architecture Definition Document. A rigorous Architecture Definition Document ideally contains: (1) a DTD (the formal description of the interchangeable form of the information), (2) a Property Set (the formal description of the ready-to-use objects and their relationships to one another), and (3) natural language text that explains the nature of the relationship between the two, if necessary including algorithms that describe the transformation between them. In effect, a Property Set can describe a specialized DOM to the specialized meanings of a particular class of information assets, while a DTD can describe the interchangeable form of such assets. This means that, in those applications of XML in which absolute precision and uniformity is required in an open, multivendor environment, and when the high cost of thinking carefully about the exact nature of the information set being interchanged can be afforded, there is a very good answer, and there is an internationally standard way to express and publish the necessary constraints. -Steve -- Steven R.
